CAUTION

The frame of the machine must be grounded. A ground terminal marked with the symbol located at the left side of the input box is provided for this pur- pose. See the U.S. National Electrical Code for details on proper grounding methods. Follow other grounding instructions per the paragraph under “High Frequency Interference Protection”.

On multiple voltage input machines, be sure the reconnect panel is connected per the following instructions for the voltage being supplied to the machine. See Figure 1 in the back of this manual.

•Failure to follow these instructions can cause imme- diate failure of machine components.

------------------------------------------------------------------------

The PRO-CUT is shipped connected for the highest nameplate input voltage. To change this connector for a different input voltage, reconnect the power straps to their respective terminals corresponding to the input voltage used.

Fuse the input circuit with the recommended super lag fuses. Choose an input and grounding wire size according to local codes or use the Input Connection table. “Delay type”(1) circuit breakers may be used in place of fuses. Using fuses or circuit breakers smaller than recommended may result in “nuisance” tripping from machine inrush currents even if not cutting or gouging at high currents.

(1)Also called “inverse time” or “thermal/magnetic” circuit breakers; circuit breakers which have a delay in tripping action that decreases as the magni- tude of the current increases.

WARNING

CYLINDER may explode if damaged

• Keep cylinder upright and chained to a

fixed support.

• Keep cylinder away from areas where it may be damaged.

•Never lift equipment with cylinder attached.

•Never allow the cutting torch to touch cylinder.

•Keep cylinder away from live electrical circuits.

•Maximum inlet pressure 120 psig (827 kPa).

------------------------------------------------------------------------

(6.3 mm) NPT thread. Tighten the air fitting to prevent leakage but do not overtighten. The use of Teflon tape to seal the connection is recommended.

Nitrogen from cylinders may be used with this machine. The cylinder of nitrogen gas must be equipped with a pressure regulator. No more than 120 psi (827 kPa) may be supplied to the regulator on the machine. Install a hose between the regulator on the gas cylinder and the gas inlet on the machine.

OUTPUT CONNECTIONS

WARNING

HIGH FREQUENCY SHOCK CAN

CAUSE INJURY OR FALL.

•Keep the cutting torch and cables in good condition.

•Secure yourself in position to avoid a fall.

----------------------------------------------------------------------------

Torch Connection

The PRO-CUT comes factory equipped with a cutting torch.

Pictures of the torch along with the required replace- ment parts are shown in the parts lists in the back of this manual. The ends of the cable to be connected to the power source are unique. Follow the applicable instructions as given in Figure 2 in the back of this manual.

Work Cable and Clamp Installation

Work cable

Work clamp

Attach the work clamp to the work cable (which extends from the front of the machine) as shown. Tighten nut and bolt securely.

AIR INPUT CONNECTIONS

A source of clean compressed air or nitrogen must be supplied to the PRO-CUT. The supply pressure must be between 70 and 120 psi (482 and 827 kPa). The flow rate is approximately 4.7 cfm (133 l/min). Oil in the air is a very severe problem and must be avoided.

Remove the plastic thread protector from the regulator input port (located on the back of the machine). Use a suitable gas connection fitting to make the connection to the available air supply. The input port is a 1/4”

OPERATING INSTRUCTIONS

Sequence of events:

A. Turn on the line power.

B. Connect the air supply to the machine.

C. Turn the power switch on.

-The green “Power On” LED should begin to glow.
